Ozonizer



, prlncipal object of my to tightly receive atented ec. 27, 1932OZONIZER Application led December 10, 1928. Serial No. 324,870.

My invention relates to ozonizers, and the invention is to provlde a newand improved device of this type which shall be simple, inexpensive,quiet, and practical, and shall be suitable for'purifying, disinfecting,and deodorizing, as in the toilet and sanitaryrooms of hotels, oiiicebuildings, railway stations, steamships, public halls, and theaters, orgenerallyin oflices, theaters, homes, railway cars, and so on. In thedrawing accompanying this specification and formingla part of thisapplication I have shown, for purposes of illustration, one form whichmy invention may assume, and in the drawing.

Figure 1 is a perspective View ofthe apparatus showing the partsseparated,

Figure 2 is a central vertical longitudinal section taken on the line 22 of Figure 3, while Figure 3 is a transverse section taken on the line3 3 of Figure 2.

The apparatus herein shown includes a rectangular sheet metal box 11comprising a base 12 provided with projections 13 carrying feet 14 whichare formed of felt to provide a cushionl support for the apparatus whenit is supported by resting upon a supporting body and are apertured at15 to permit the passage therethrough of screws by which the device maybe attached to any desired support in any position either uprlght orotherwlse. The casing 11 also comprises a top 16 spaced from the base 12and oo n-` nected thereto by two sides 17 outwardly displaced at 18 toform recesses 19 contoured and maintain tightly compressed the laminatedcore 20 of a transformer 21. The core 20 of the transformer 21 consistsof two side sections 22 connected by three cross legs, a secondary coilleg 23 about which is wound a suitable secondary coil 24,*a primary leg25 about which is wound a suitable primary coil 26, and a leakage leg 27provided to increase the action of the device.

Encircling the secondary co1l 23 are three separate parts, an innerelectrode sheet 28 connected by a conductor 29 to one terminal of thetransformer secondary 24, an outerv electrode sheet -30 having a freeend 31 extending over the primary coil 26 to be grounded at 32 to theleakage leg 27 of the transformer core 20 which is in turn con- Theelectrode sheets 28 and 30 are prefer'v ably rough-surfaced, to increasethe ozone generating action thereof, and formed of oxidation-resistingmaterial, to reduce to a minimum vaporization of the metal into the aircurrent; I employ herein aluminum wire mesh, and ind that verysatisfactory from bot-h points of view, it is distinctly roughsurfaced,and there is practically no vaporization whatever.

The transformer windings and the associated parts are insulated from thecasing 11 by means of two insulating trays 35 forming i'n effect alining for the casing 11. The two ends of the casing 11 are closed byend plates 36 held in position by bolts 37 passing through apertures 38and 39 formed respec tively in the end plates 36 and in ilanges 40 onthe casing sides 17. The end plates 36 are also provided with apertures41 to permit entrance of air into the casingL 11 and exit from thecasing 11 of the air and the ozone, whileone of the end plates 36 isprovided with a screw-threaded aperture 42 in which is received aninsulating bushing 43 through which pass conductors 44 for connectingthe primary coil 26 to a suitable source of electrical energy.

It will be understood by those skilled in the art that in operation arelatively low potential alternating current, for example current at 110volts, is supplied to the transformer primary coil 26, and that as aresult there is induced and generated in the transformer secondary coil24 an alternating current of ico relatively high potency, say in theneighborhood of eight or ten thousand volts, and that inasmuch' as thesecondary coil 24 is connected to the two electrode sheets 28 and 80 thegeneration of this alternating high potential in the secondary coil 24imposes upon or-between the two electrode sheets 28 and 30 a highalternating potential dierence toolow to `cause puncture but high enoughto effect from the electrode sheets 28 and 30 a substantially Asilentdischarge eHective to produce ozone from and in thesurrounding air, alsothat the disclosed construction of the electrode sheets .28 and 30facilitates the production of ozone and increases the quantity thereof,and that the composition of the electrode sheets 28 land 30 decreasesthe amount thereof vaporized by the discharge. In practice I find toanextent wherein the deterioration is entirely negligible and the vaporization of the sheets cannot be noticed either upon examination of theelectrode sheets or by any odor in the air or ozoneemergmg from thedevice.

Under these circumstances it will ob-` vious to those skilled in the artthat I have provided anew and improved ozonizer, and accordingly that Ihave accomplished at least the principal object of my invention, alsothat my invention embodies advantages other than those specificallypointed out or suggested herein, also that the particular embodiment ofmy invention herein shown and described may be variously vchanged and'modied without departing from the spirit ofl my invention or sacricingthese advantages, accordingly it will be understood that the disclosureherein is illustrative only, and that my invention is not limitedthereto.
